How to reproduce:
1. Download and open the attached project
2. Build Addressables by going to "Addressable Groups" > "Build" > "New Build" > "Default Build Script"
3. Open the "SampleScene" scene
4. Enter "Play" mode
5. Observe the Console window

Expected outcome: No errors appear
Actual outcome: "OperationException : Unknown error in AsyncOperation : Resource<IAssetBundleResource>" errors appear

Reproduced with: 2020.3.46f1, 2021.3.21f1, 2022.2.11f1, 2023.1.0b8, 2023.2.0a6

1. I implemented a http server to simulate the bad network condition. In this situation, synchronous loading of remote AssetBundles throws exceptions when first download failed and doesn't try to download again even RetryCount is greater than 0.

2. 1) Select 'Use Existing Build' in Addressables Groups window
2) Build Addressables
3) Open 'SampleScene.unity' and enter Play Mode
4) Observe the Console window

Expected result: There is no error in the Console window and the prefab is loaded
Actual result: There are erros in the Console window and the prefab is not loaded

5) Select 'AddressableAssetSettings.asset' and set 'Max Concurrent Web Request' to 2
6) Repeat step 2-4, note this time there is no error in the Console window and the prefab is loaded
